The flanges 14 are provided with upwardly-turned ends 14h, which form i troughs in which the ends of the units 9 and the flanges 15f1 fit. The to 15 is formed from the Vsame sheet of meta that forms the front, rear, and bottom walls of the chamber 11, the two edges of the sheet of metal being united at the rear by turning the upper edge rearwardly and upwardly to form a trough 15e and the lower edge downwardly to rest in the trough, as at 15". The walls of the lower portion 112 of the chamber 11 are tied against expansion by a thimble 23, bearing against o posite walls, and a rivet 24, passing through t e thimble. The bar 18 consists ofv a sheet of sheet metal having its edges bent upwardly at 18a and then downwardly at 18b to strengthen the same. The end walls or legs 16 are formed with flanges 16h, which contact with the outer Wall of the chamber 11, while plates 16"', secured by bolts 16d, engage the inner :wall to grip the edges of the sheet of metal. The troughs formed at the joint between the units and the chamber 11 and at the joint at the rear Wall ofthe chamber 11 serve to trap a portion of zinc, into which the radiator is dipped after being assembled. If at any time the radiator should become so hot as to melt the zinc, the troughs will prevent-,it from running fromthe joints.

The embodiments herein shown and described arc for the purpose of illustration and it is to be understood that I may within the scopeof the appended claims Various changes without departing from the spirit or sacrificing any of the advantages of my invention.

Having described my invention, what I claim is 1. In a radiator-heater, the combination with a plurality of alined radiating units, of a generator having its bottom, top, frontand rear walls formed of sheet metal into an upper chamber, openingat its top into the lower .ends of all the units and an elongated lower reduced portion, cast-metal end walls forthe generator, having legs formed thereon,\and

2. In a radiator, the combination with a plurality of units, of a chamber connecting the units, a bar within the chamber, and tierods within the units and secured to the bar 3. In a radiator, the combination with the units, of a chamber, flanged sleeves connectthe units and holding the units and chamber together. l

4. In a radiator, the combination with the units, of a chambenmsleeves provided with troughed flanges and connecting the units chamber andbearing against thesleeves, and tie-rods positioned within the units and e11- gaging the bar.

5. In a radiator, the combination with a plurality of units, of a chamber connecting the unitsfmeans tying opposed walls of the units, and tie-rods supported wit-hin the units by sai'd tying means.

6. In a radiator, the combination with a plurality of units, of a chamber connecting the units, thimbles connecting opposed walls of the units, tie-rods supportedfrom the thimbles Within the units, and a bar positioned within the chamber and having the tie-rods secured thereto; i

7. In a radiator, the combination with a plurality .of units, of a chamber, flanged sleeves fitted through the chamber and into the units, thimbles connecting opposed walls of the units, a bar positioned within the chamber and bearing against the sleeves, and tierods connecting the thimbles and the bar.

8. In a radiator, the combination with a chamber provided with openings, of inwardlyextending flanges surrounding the openings, radiating units fitted within the openings and bearing against the flanges, and sleeves provided with troughed flanges embracing the flanges on the chamber and the ends of the units. v

9. In a radiator, the combination with a plurality of units, of a chamber connecting.

and having the bottom, front and rear walls ,l

bent from a single sheet of metal to forman enlarged upper portion and a reduced `e'lngated lower portion, and an asbestos covering for one o portion.

11. In a radiator-heater, the combination with the radiating units, of a generating-` `chamber positioned below and connected to 'the same and having its bottom, front and re-arwalls bent from a single sheet of metal to form an enlarged upper portion and a re'- duced lower porton and cast-metallegsformto hold the units. and the chamber together.

12. In a radiator-heater, the combination with the radiating units; of a generatinging the units and the chamber, a bar fitted Within the chamber, tie-rods fitted within chamber havin it'sftop,'bottom, front and rear walls bent rom a single sheet of metal to form an upper enlarged portion and a lower reduced portion, the. edges ofthe metal being united by bending the upper edge upwardly to form a trough and the lower edge downwardly into the trough; cast-metal legs formthe walls of the reduced lower IOO ` .Sing 4the end iwalls of rthe .ehaIr-ilwlr;` and a and.'v the lover edge donvmmrdlyYinto-Chairei burner playing upon the lower reduced por'- trough. 4 A tion ofthe 'generating-chamber.' .y f The foregoing speciication signed this 17th 13; In e; radator-'heater'the combination day of August, 1904. u
